Add a new entity type for custom data based on the field framework with templates and fieldtypes
In many project we need to add data that's not directly related to pages or products and we often add custom tables to the db to support this data. Instead I think cutom data based on the field framework would be a good alternativ for this.
And also support for editing this data in backoffice in a similar way as the products with a tree structure.
Maybe also with support to add this data to the search engine.
